THREE-ROLL INK MOTION.

Application ma June 15, i926, serial No. 116,072. Renewed .my 25,- 192s.

T hisI invention relates to an inking device forrotary printing presses. The'principal object ot the invention is to provide an arrangement ot ink distrilniting` rolls of such y nature that thc plate cylinders can be inked by three rollers -without the necessity ofv employing a removable ink carriage.

Reference is to be 'had to the accompanying drawing which is a. side view of a press partly diagrammatic in form showing both inlring systenxs, one of them on theright in the normal running position and the one on the left in the position assumed when the central roll is moved away from the plate cylinder for any purpose.

'Ordinarily in newspaper presses, twov form rollers are employed for applying the. ink to each plate cylinder. W' hen more than two form rollers are-used, as in the case of magazine printing,'it is necessary to have the Vink motion roll away from the 'form in orderto make it possible to remove the inside form rollers. The principal objectof this invention is to avoid this and eliminate the removable ink carriage heretofore thought necessary;

The invention is shown as employed with an ordinary ink fountain10,ountain roll 11,` pick-up roll 12, and distributing roll 13 receiving ink indirectlyfrom the piek-up roll by another roll 14. The distributing roll applies the ink toa primary inl: 'cylinder 15 which, by means Vof. two transfer rollers 17 and 18, delivers ink to the secondary ink cylinders 19 and 20. These ink cylinders I transfer ink to the plate cylinder 21 by ordinary form rollers 22 andan intermediate form roller 23. In this case the form roller 23 receives ink from one of the link cylinders 19 the same as one of the form rollers 22. It is of smaller diameter so that irregularities of inking by either form roller will not be repeated on the plate cylinder in the same relation to those of the other. The other form roller 22 is the only path through which ink is delivered from the ink cylinder 20'to the plate cylinder 21'.

ItV will be understood that these various rollers are geared together so as to rotate at desired surface speeds, which in ordinary cases are the same for all the rollers and equal to the surface speed 'of the cylinder 21. The gearing is not described in detail as that is provided for in a well known way.

outwardly and downwardly. The bearings of the transfer roll 17 aremounted on ifrainesf26 pivoted on the axis ofthe ink cylinder 15. A handle 27 is provided for swinging this bearing frame 26 and a con- Vvenient means is provided for holding it in the position shown on the right in the drawings where. it is in contact with the ink cylinder V19. y

The roller also is mounted in bearin 28 on the frame 25 from which-it can released and* carried down by hand and swung around to thelposition' on the left tov get it out in front where it is readily accessible. Itis for this reason that the cylinders 19 are mounted on the overhanginglugs and the frame 26 is made to swing onthe Shaft of the cylinder 15 down into theposition shown on the left in the Vdraw-- ing. This clears the way for thev form roller 23. A comparison of the positions shown on the right and leftv of the figure shows the-whole motion and makes it clear that this exposure of the'form roller 23 is possible by this arrangement. p.

Although I have illustrated and described only one form of the Vinvention and shown it as applied to a particular inking system, am awareof the fact that it.' can be applied to other 'systems and that modifications can be made by any personv skilled in the art Without departing from .the scope of the invention as expressed in the claims.

Therefore I do not Wish to be limited to all the .details of construction lherein shown and described, but what I do claim is 1. In an ink motion, the combination with three form rollers, arranged to contact with a single plate cylinder, an ink cylinder forV delivering ink to certain of said form rollers, a transfer roller supplying ink to the ink cylinder, and means whereby the transfer roller can be movedl away from its operative position to permit the inner one of the two form rollers to be taken out throu h the space normally occupied by said trans er roller.

2. In an ink motion, the combination with .two form rollers arranged to transfer ink to the `same -iplate cylinder, of an ink cylinder for 4,supplyifng ink Yto both form rollers, a roller for transferring ink to the ink cylinder, and means for Vmounting the bearings `of the last'. named roller movably j so that it can lbe moved bodily away from the ink cylinder to leave a space through which one of the .form rollers can be removed.

In an,v ink motion, the combination with a frame having overhanging lugs on its sides for, supporting bearings, an ink cylinder Supported in said bearings, and a removable form roller supported in such manner relattiveto the ink cylinder at the innerY side of said lugs for .transferring ink-from the ink cylinder toa plate cylinder vthat the form roller canbe taken `out around and underl the inlreylinder; Y i Y 4'. In an ink motion, the combination with a frame having overhang-ing lugs on its sides for supporting bearings, an inkgfcylinde'r supported in 'sa-idf bearings, a removable form Vroller supported' at the inner side-.of

'saidlugs :for transferring ink from the ink cylinder toa plate cylinder, and a roller for transferring ink to Vthe ink Cylinder, removably located nearthe bottoni of the ink cylinder, whereby .the Vform roller can `be .taken outaround and under the ink cylinder'.

`5. In an inlring system, the combination with 'aplate cylinder, of three forinrollers for delivering inl; thereto,'two ink cylinders together' delivering ink ntoV the three form Y rollers, transfer rollers for delivering the ink f tothe ink cylinders, the central form roller V`being loeatedrbetween the inlrcyliiidersand A with a'plate cylinder, ofV three form. rollersV for delivering' ink, thereto, two ink cylinders the Vouter transfer roller being mounted on a pivoted frame to-l swingr down: soV that vit will'leave -a space for the removal of the central form rollen Y f v 6.'
